The elements 5, 6, 7 are ancre clearly shown 4and' described lin fthe-application aforesaid and are -not o'laimecll in ithis application.

A combined connecting and adjusting means, iin iaccordance with this linvention, for aseat unit or structure, comprises the pedes- -tafl l, afseaft bracket forming -an element' of "the :seat unitorstructure, afbinder `or helder member anda plurality `olf clamping elements, :and 'said Imeansnot ionly removably connects Lthe V.seat iunitjor ystructure 'to the pedestal, y'but also ifiXedl-y -secured it in adjusted position.v

The Vped'e' tal low casting 'having-atapered shank-18 and a zbase-"9 provided with ope'ningsvi'() for the passage-off hold-ffa'stf devices Ito lfiXe'dly secure the base to the fiioororothefr suitable 'I support. The hollow Apedest/al iseonst'rue'te'd in a #manner to provide ithe passage or socket 4 to conform ito fthe shape-of the standard 2, -as showno polygenialfcbntour ,ff- Bhe yfrom lis constructed'from a hol- 12, is a pair of lengthwise extending and of the shank 8 is flattened, as at 11, for-a substantial portion of its leng'th and with such flattened portion extending from the top edge of the pedestal. rllhe said flattened portion 11, at its lower end, terminates in a forwardly directed shouder 12. Formed integral with the front of the shank 4 and extending from the top thereof to the shoulder forwardly directed opposit'ely disposed spaced flanges 13, 14, and each of which is angle-shaped in cross section, see Figure 2.

A he forward portion of each of the flanges yis disposed at right angles and extends inthe fiat portion 11, form the front of the shank 8 with a vertically disposed pocket 15" which is T-shaped or dove-tail in cross section. The pocket 15"extends from the top of the pedestal to the shoulder 12, and is aA part of the combined connecting and adjusting means for the seat unit. The teeth of the flanges 13, 14 provide a pair of racks and form elements of the combined connecting and adjusting means for the seat unit.

The supporting bracket for the seat member 16 and seat back 17 is indicated at 18 and is of U-shape contour or of yoke shape. The rear face of the bracket 18centrally thereof, is formed with a vertically disposed groove 19, of substantial width, and projectingv from each side wall of the groove 19, as well as being formed integral therewith and with the bottom of the groove, is a plurality of teeth 2O.` Each of the teeth 20 is of a length to terminate at a point removed from one side of the vertical median of the bracket 18. A pair of superposed spaced openings 21 is arranged at the vertical median of the bracket 18, and the latter, centrall of its forward face, is formed with a notc y1 22, which extends from its top edge and terminates in the bottom of the groove 19. The bottom of the notch is rounded. The bottom edge of the bracket 16, centrally thereof, is provided with a notch 23 having rounded side walls. The side walls ofthe groove 19 are rounded.

The bracket 18 is vertically adjusted on the flange 13 and 14 and when adjusted the teeth 20 engage in the teeth 15. For securing the bracket 16 in adjusted position, the

binder or holder member and the pair of clamping elements are employed.

The binder or holder member consists of a vertically disposed rectangular body portion 24 having the corners rounded,asy at 25.

Formed integral with the forward face of largement as well as projecting forwardly therefrom, is an angle-shaped supporting lug 29. Formed integral with the bottom of the enlargement, projecting forwardly therefrom and at right angles thereto, is a lugI 30. rlhe lug 29, when the binder member is in position, within the pocket 15', extends outwardly between theA fianges 13, 14, through the notch 22, and overlaps the top edge of the bracket 18. The lug 30 extends outwardly between the flanges 13 and 14 and through the notch 23. c n

The binder member, centrally thereof, is formed with a pair of spaced openings 31, 32, having threaded walls, and which register with the openings 21 formed in the bracket 18. lThe groove 19 is of a width to overlap the flanges 13 and 14 when the supporting bracket is mounted in position. The supporting bracket carries the binder .member and when said bracket is mounted in position, the body portion 24 of the binder member, as well as an enlargement 26 thereof, is arranged in the pocket formed by the flanges 13, 14. Y The body portion 24 is positionedbetween the horizontal legs of the flanges and the flattened portion 11, andthe enlargement 26 lextends between the horizontal legs of the flanges 13, 14. lThe lugs 29 and 30 project over the top and bottom edges of the bracket 16.

The binder member is secured in position for the purpose of maintaining the teeth 20' in engagement with certain of the teeth 15 of the flanges 13 and 14 through the medium of a pair of clamping screws 33, one of which extends through an opening 21 and has threaded engagement with the wall of the opening 31, and the other of which extends through the other opening 21 and has threaded engagement with the wall of the opening 32. When the binder member is secured in position by the clamping screws 33, the teeth 20 are held in engagement with certain of the teeth 15 and which maintain the supporting bracket in the position to which it was adjusted.

To release the seat supporting bracket, the lower clamping screw 33 is loosened freely and the upper one given a few turns, after which the bracket can be lowered and raised on the hinge principle, a slight raise of the entire bracket and it moves freely. Drop the entire bracket and it locks automatically.

It is thought'that the Vmany advantages of a combined connecting and adjusting means, in accordance with this invention, vfor a seat unit or structure, can be readily understood,

yet it is to bey'understood that changes in the `v details of construction can behad which fall withinthe scope of the invention as claimed. v l
